Two red salts derived from yellow 4-cyano-1-methylpyridinium iodide: 1,1′,1″-trimethyl-4,4′,4″-(1,3,5-triazin-2,4,6-triyl)tripyridinium trisiodide and 4-cyano-1-methylpyridinium triiodide

Two red salts were obtained unexpectedly from yellow 4-cyano-1-methylpyridinium iodide. Crystal structures of 1,1′,1″-trimethyl-4,4′,4″-(1,3,5-triazin-2,4,6-triyl)tripyridinium trisiodide (m.p. 383 °C) and 4-cyano-1-methylpyridinium triiodide (m.p.118 °C) are described.65
